BubbleUPnP does not play BBC HD radio streams

I have bubbleUPnP installed on a Samsung Galaxy 4 Tablet. When I enter the URL below into BubbleUPnP, (I've had to remove 'http' from the link so that this message would post)the app thinks it's a video and opens my video player app. It plays the sound but obviously it's not what I want. When I choose an external renderer to send to my HiFi, which is what I really want to do, then the screen shows the film strip image (instead of the headphone image for audio) and indicates it's a MP4 file and nothing happens. I'd be grateful for a fix to this problem as I'd like to be able to play the BBC 320Kb AAC streams to my HiFi.
